You didn't mention the tank size, but this will work for ANY tank:
Fill your tank with gas (only), exactly how much you need. Scratch mark your tank or make a small dipstick for exact measurement. Disconnect your fuel line and drain the gas into a measured container. That will tell you EXACTLY how much gas is in the tank @ the scratch mark or dipstick. Measure the amount in ounces, then divided by 100.
That is the exact amount of Opti-2 oil you need for the mix. Be sure it's oil made to mix 100:1, or you'll damage your engine.
